Sammy Lightfoot is a 1983 computer game by Sierra On-line. The game was released for a number of 1980s-era home computers and game consoles, including the Apple II, the Atari 400 and 800, ColecoVision, Commodore 64, and the IBM PC. A multi-level platform game (or "climbing game," as the genre was called in the U.S. in 1983) in the vein of Donkey Kong, Sammy Lightfoot follows the travails of a circus worker who jumps and climbs through a number of perilous situations.
